      I took my digital caliper and set it to your dimension and checked across the coils. I had a reading of 4.464. This is from the original installation of the new coils. Do you think I can set the air gap this way bearing in mind to watch the circumference points of the coils not touching the flywheel.

        Yes, before I made the ring, I used to line up the coils with the boss and check with the caliper. It worked OK too but with the ring, it would be a quicker set up.

            How do I check continuity from end of spark plug wire to the coil?

              These systems are so simple. If the parts are good, you can almost always put a no spark condition down to either something grounded out that shouldn’t be or wires run to something they shouldn’t be.

              You haven’t answered my original question. Did you verify that the coils are connected to the proper set of points? You can set the coil positions and test the shit all you want. If the coils are hooked to the wrong set of points, it will not fire no matter how mad you get at it. Or me. Not that I care, lol.

              All of this crap about air gap and distances and using setting rings is overthinking personified. Jeez. I’ve been setting OMC points since I was a kid and never used any special ignition tools or devices. I use a screwdriver to remove and replace them. I use my effing thumb to position them on the mag plate. The coil heels can only get shoved in so far. The only thing I’ve ever worried abuot is if the heels hit the flywheel or not. If they hit, shift them inward. If they don’t hit, leave it alone. I’ll stack any motor I’ve tuned up against anybody elses. I’ll guarantee you that theirs won’t run any better than mine, whether they used special tools or not. It ain’t rocket science, eh.

              Best,

                Here are a couple pictures. One of the old and the new. I believe they are right. Let me know if you disagree.

                    How do I check continuity from end of spark plug wire to the coil?

                    with coils primaries connected (one is grounded)

                    stick one probe of the VOM in the plug boot spring clip and one touching the engine body set the meter above 10K ohms range or better yet use a digital meter

                    you MUST see 4-8Kohms on each wire if not the coil secondaries are open or the plug wires are open

                    simple test … post results

                        Look good to me! you should get the spark.
